Russound MCA-C5 User and Installation Manual
Linked Controllers
MULTIPLE CONTROLLER INSTALLATION
Linking Multiple Controllers
The RNET Link In and Link Out can be used to connect two or more (up to 6)
MCA-C5 controllers (does not support CAV6.6, CAM6.6 or CAA66 controllers).
The connection is made using a CAT-5e patch cable from the Link Out of the
rst controller and into the Link In of the next controller. Along with RNET data
signals, the RNET Link In and Link Out port passes source IR signals.
The CAT-5e patch cable must have an RJ-45 connector on each end with
T568A wiring conguration. It can not exceed 18 inches (45.7 cm) in length
to avoid potential cross-talk between the source-specic IR repeating signal
lines.
Controller ID Switch Settings
The Controller ID switch is a rotary switch with seven positions. It is used to set
the controller ID number for multi-controller systems, and to put the MCA-C5
into Firmware Update mode.
If two or more MCA-C5 controllers are connected using the RNET Link In and
Link Out ports, each controller must have a unique controller ID prior to being
connected through the RNET ports. Set each controller’s ID switch to a unique
number. Any multi-controller conguration requires that one controller be set
to controller ID #1. This action must be performed before the system setup
procedure is completed through SCS-C5 software and before powering up the
system. The small arrow on the dial should point at the desired setting.
